. STEAM-TRAP.

SPECIFICATION forming part of Letters'Patr-,nt No. 645,506, dated March 1e, 1900.

Applicationfrua February 17,1899. sera1N0. 7o5,7sa. (No man To all whom, it 17tctyco7e0ern: j Be it known that I, HENRY HELLING, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State of Colorado,have invented certain new and useful Improvements `in" Steam-Traps;

\ and I do declare the followin g to be a f ull,clear, and exact description of the invention, such las will enable'others skilled in the art to which it appertains to make and usethe siameLreference being had to the accompanying'drawmgs, andto the iigur'es ot' reference marked* j thereon, which form a part of` this specification; g My invention:relates to improvements in steam-traps, my object being to still further. improve the construction set forthl in my for- I mer patent, No. 610,862,-dated September 1,3, 1898 v'and tothese ends the'invention vconsists of the features hereinafter vdescriberl and claimed, all of which will be fully vunderstood by reference to thepaccompanying drawings,

in which is illustrated an embodiment thereof.

In the drawings, Figure l is a vertical longitudinal section taken through my improved steam-trap. Fig.y 2 is'a fragmentary section taken on the line Y Y, Fig. 1.l Fig. 3 is a section taken on the line X X, Fig. Similar reference characters indicating corresponding parts in the views, let the numeral 5 designate a casing which occupies a vertical position, its top being. provided with an opening whereby it is adapted to be connected with the steam-pipes of ya system; The bottom of this casing is closed by a head 6, which is provided with a ange engaging a flange on the bottom of the casing. The head is fastened to the casing bypassing bolts through' registering apertures formed in the engaging iianges. The head 6 is provided with an opening or passage 6a, whose outer extremity is threaded to connect with a conduit (not shown) leading to the sewer. In this bottom head is formed a central threaded opening communicating with the passage-way 6a and into which is screwed a valve-chamber 7, having a central opening into which is also screwed a plug 8, in which is formed an escape-orifice 9, through which the water passes to the opening 6", The upper part 7a of the valve-chamber is apertured to receive a rod or stem 10, which tits closely therein and lower extremity of the stem is formed into a Valve 14, adapted to engage a seat 8a, formed inthe plug Searound thev top'of the escape-f orice 9.\ .The top of the Valve-chamber is perforated around the opening through which by means of a nut 1 6, located in' a stirrupshaped coupling attachedto the bottom ofthe vfloat and adaptedto screw upon the upper threaded extremity of the valve-stem.

At onev sideof the bottom ofthe casing is foi-median opening 25, leadin gto an upwardlyvprojecting y'passage-way 17, whose upper eX-V tremity formsa junction with a passage 18, leading downwardly and connecting with the opening 6? byway of an orifice 19formed in Vthe bottom 6 of the casing. f Located atthe junction of thepassage-ways 1,7 andl 18 is a valve 20, providedwith a screw-stem 21, having a lhand-wheel at its outer extremity. The valve 20is adapted to engage a seat surround- Aing the top of the passage 17,whereby communication between the two passages 17 and 18iscut o when the valve is closed. Thisvalve 20 is .norm ally closed, and the passages 17 and 18 are only utilized when it is desired to cleanse the casing of any dirt or sediment that may have accumulated therein.

In using my improved devicethe opening i linthe top of the casing is connected with the lowest part of the steam system, whereby the water of condensation finds its way thereinto. When there is not enough water inthe casing 5 to raise the float, .the valve 14 is closed; However, as the water of condensation accu Vmulates in the casing a water seal is first formed in the bottom of the casing below the i'loat, and as the accumulation of water continues and passes up around the float the latter will be raised, thus opening the valve 14 and allowing the water to escape, first through the perforations in the top 7a of the valvechamber and thence through the orifice 9 to the passage-way 6a, leading to the sewer-con duit. The waste water continues to escape until the gravity of the float and its attach- 6o the Valve-stem 10 passes for the admission of waterfrom the surrounding receptacle. The

upper extremity of the valve-stem is adjustably connected with the-bottom of a float 15 f ments closes the valve 14 and shutsoff the escape. It Will be readily understood that while the valve 14 is open no steam can escape, by reason of the constant water seal in the bottom of the casing. Since the valvechaniber 7 is closed except' by way of the small perforations in the top of the chamber, there is no opportunity for dirt or sediment to enter and stop the orifice 9.

Then it is desired to clean out the casing, the valve 2O is opened and the force of the steam Will drive out through the passages 17 and 18 all the sediment or foreign particles of matter that may have collected in the bottom of the casing-chamber.-

Having thus described my invention, what` I claim is i i In a stea1n-trap,the combination with a reeeptacle connected with a steam system and arranged to receive the Water of condensation therefrom, means for automatically discharging the Water from the receptacle, Wherebya water Seal is normally maintained in the rereceptacle being provided With a passage ceptacle to prevent the escape of steam, said leading from its bottom upwardly, and thence downwardly to an outlet-opening, and a valve located at the upper extremity of the said passage. 4

`In testimony whereof I affix my inpresence of two Witnesses.
